Invoice

Apologies in advance, I know this subject is tedious to the long-standing members.

Getting a legitimate green book/tabiyanrot on anything other than a BMW or some Triumphs is not an easy task.

Some bikes are offered with "Invoice". Is the "invoice" actually anything of value and can it lead to a proper registration? Do "invoices" vary in their legitimacy as do the green books, and how do you know if you are getting anything of value as opposed to just a scrap of paper?
